What They Say
“Cowan is by far the best firm we’ve worked with and Jonathan Z. King is the principal reason. . . .In [one] case . . . the company threw a ton of money and resources against us, with a large trial team . . . but Jonny simply ripped them apart with his courtroom abilities and his sharp analysis of trademark law supporting our case. He’s so smart and really understands our business, but is also incredibly unpretentious and down-to-earth.”
2018 Law.com“Joel Karni Schmidt has been advising and assisting my clients with trademark filing and prosecution for the past 15 years. I worked closely with Joel on multiple matters and he is an excellent attorney. He is very efficient, always recommends the best and most cost-effective approach, is extremely experienced and thus knows how to solve the problems, and just as important – he is very nice and pleasant to work with.”
2022 The Legal 500Mary Donovan “demonstrates exceptional resourcefulness and judgement, and guides her clients in a way that is sensitive to their budgetary concerns. She is well connected and highly regarded in the wider trademark community, and has excellent relations with local counsel worldwide. She is a pleasure to work with on all aspects of trademark prosecution, enforcement and litigation, as well as unfair competition, internet and advertising issues.”
2022 WTR 1000 – The World’s Leading Trademark Professionals“The team at Cowan, Liebowitz & Latman is fabulous. They are such special people. They have a unique way of maintaining relationships with their clients and their international network – they know also how important their international network is in order to be good for their client and therefore cherish this network. It is one of the nicest firms I have every worked with. It is just like family, but still all very high-end in terms of quality. They send us work, but we also send them work. Both ways it works!”
2021 The Legal 500”In cases where settlements are possible, [CLL's] lawyers will always foster settlement. However, in cases where they have to litigate hard, they do. Moreover, the time given to each matter is ample despite their busy schedules. I’ve always found that they make clients feel special and, often, the feeling is that my matter is the only matter they are handling because of the constant care given to it. This is rare in law firm partners.”
